CCR3 (C-C Motif Chemokine Receptor 3): CCR3 is a chemokine receptor important for the recruitment and activation of eosinophils, basophils, and T cells, playing a critical role in the body's inflammatory response and in the pathology of allergic diseases. It is a key receptor for eotaxin, a chemokine involved in eosinophilic inflammation, such as that seen in asthma and allergic rhinitis. Dysregulation of CCR3 signaling has been implicated in the exacerbation of allergic and inflammatory conditions, highlighting its potential as a target for therapeutic intervention in these diseases....
